In this study involving wives of active-duty U.S. Army soldiers, women whose husbands were deployed to Iraq or Afghanistan between 2003 and 2006 were more likely to receive diagnoses of depressive, sleep, anxiety, and stress disorders than were women whose husbands were not deployed.

In this study of injured U.S. military personnel, the use of morphine during trauma care was associated with a reduced risk of post-traumatic stress disorder (PTSD) after injury. This finding suggests that optimal control of pain after serious injury may help prevent PTSD.

In this 12-week randomized trial comparing two biologic agents known to be effective for psoriasis, ustekinumab (an interleukin-12 and interleukin-23 blocker) was more effective than etanercept (an inhibitor of tumor necrosis factor α). Adverse events associated with the two treatments were similar, but the trial was not large enough and follow-up was not long enough to assess uncommon adverse events.

Preoperative biliary drainage is often performed in patients with obstructive jaundice caused by cancer of the pancreatic head, but the benefit of the procedure is unclear. This randomized trial compared 4 to 6 weeks of preoperative biliary drainage, followed by surgery, with immediate surgery alone for cancer of the pancreatic head. The drainage procedure increased morbidity and did not decrease the rate of surgical complications.

A donor trachea, harvested from a cadaver, was transplanted into the forearm of a recipient and wrapped in the recipient's fascia. Months later, a vascular supply to the allograft had become established, and the tracheal epithelium had repopulated with a buccal mucosa graft from the recipient. Immunosuppressive therapy was stopped, and the allograft was used to repair the recipient's tracheal defect. The graft continues to function more than 1 year later.
